Final answer:
Stress and strain are different; stress measures the force causing deformation, while strain describes the deformation itself.
Step-by-step explanation:
The statement 'Stress is another term for strain' is false. Stress and strain are related but distinct concepts in physics. Stress is defined as the ratio of the deforming force F1 to the cross-sectional area A of the object being deformed and has units of N/m2. It is a measure of the internal forces that cause deformation. Strain, on the other hand, is the ratio of the change in length to the original length, and it is a unitless quantity that describes the deformation itself.For example, tensile stress happens when a material is pulled at both ends, whereas tensile strain is the resulting elongation or stretch in the material. Similarly, compressive stress causes shortening, and the corresponding strain is called compressive strain. Shear stress deforms the material by sliding layers upon each other, and shear strain quantifies that deformation.
